✔ 最佳答案
Because metal has a low specific heat capacity which means it is easy to be heated up and easy to have energy loss.However, wood has a higher specific heat capacity compare with metal.Thus a pair of metallic chopsticks feels colder than a pair of wooden chopsticks, even they are at the same temperature

As metal is a good conductor of heat while wood is a poor conductor of heat, heat loss will be greater in the metallic chopsticks

the metallic chopsticks conducts the energy away from your hand more easily and thus you feel colder than a wooden one.
